The compression elastic piece 8 is sleeved on the connecting column 6.
The limiting protrusions 31 and the limiting grooves 41 are arranged in 4 groups, the circumferences of the limiting protrusions and the limiting grooves are distributed at equal intervals, and the included angle is 90 degrees. As shown in fig. 2-3.
The cover body 5 and the first moving part 3 are provided with a sinking groove 9 on the outward facing surface, the through hole 34 on the first moving part 3 is positioned in the sinking groove 9, and the bottom of the sinking groove 9 on the cover body 5 is provided with a through hole 91. The end (head) of the connecting column 6 sinks in the sink 9, as shown in the attached fig. 1-2; the head of the screw 7 sinks in the sinking groove 9 on the movable piece one 3, as shown in figure 3, the end of the screw 7 passes through the through hole 34 to be in threaded connection with the screw 7 and the end of the connecting column 6.
